Abstract: Doping of Bi12TiO20 with Ba ions was prepared by a chemical solution decomposition (CSD) method. Crystal structures of the prepared powders were confirmed by XRD and IR methods. Photocatalytic activities of the prepared samples were evaluated using methyl orange as a model organic compound. The result shows doping with 0.5 at.% Ba2+ can significantly increase the photoactivity of the Bi12TiO20 crystals. [Copyright &y& Elsevier]
